ONLY AT DEAN & DELUCA. For their roasted and lightly salted pistachios, Lebanese company Castania imports the finest raw pistachios from Iran and roasts them following traditional roasting methods that remove the moisture from the nuts without harming the alkaloids that give them their flavor. Specially packaged to protect against sunlight, oxygen and humidity, these intensely flavored in-shell pistachios arrive at your doorstep fresher than other nuts, and have a longer shelf life.
